Problems solved by technology

Foams and, in particular, foam emulsions are complicated systems which do not form under all circumstances.
Changes in foam emulsion composition, such as by the addition of active ingredients may destabilize the foam.
The alcohol promotes fast drying and thereby attempts to address the sticky feeling left by many topical formulations after application; however, alcohols, and in particular the methyl, ethyl and isopropyl alcohols preferred in the '920 patent, are defatting agents and may cause skin to become dry and cracked.
Alcohol is known to impair the integrity of the skin barrier, dry the skin and cause skin irritation.
Moreover, the respective incidence of skin irritation caused by the vehicle of these foams is 75%.
